  • Patent number: 7022546
    Abstract: A wafer cap protects micro electromechanical system (“MEMS”) structures during a dicing of a MEMS wafer to produce individual MEMS dies. A MEMS wafer is prepared having a plurality of MEMS structure sites thereon. Upon the MEMS wafer, the wafer cap is mounted to produce a laminated MEMS wafer. The wafer cap is recessed in areas corresponding to locations of the MEMS structure sites on the MEMS wafer. The capped MEMS wafer can be diced into a plurality of MEMS dies without causing damage to or contaminating the MEMS die.
    Type: Grant

  • Publication number: 20040236754
    Abstract: A method of maintaining a bidirectional link between data in a file checked-out from a content management system to a user computer and data in at least one file maintained at the content management system is provided. In the method, a first file is scanned at least when it is one of checked in and checked out of the document management system to locate a link in the file. Information is gathered from the first file regarding a source and target of the link. It is determined if an element in the file is the source or the target. The information is the stored in a database. The information in the database is automatically updated when a second file is corresponding to the other end of the link is checked in to the document management system to reflect changes made to the end of the link in the second file. The changes are applied to the information in the first file.
